Duplicate remover & line sorter
Paste a messy list and clean it up in a couple of clicks. Operations chain, so you can deduplicate, then sort, then number, without moving the text between tools.
How to use the duplicate remover & line sorter
- Paste your list into the input.
- Click the operations you need — each one applies to the current output.
- Copy the finished list.
How it works
Deduplication keeps the first occurrence of each line and drops later ones. With the case-insensitive option ticked, lines are compared after trimming and lower-casing, so ' Apple' and 'apple' are treated as the same entry.
Sorting uses your locale's collation rather than raw character codes, which puts accented characters where a reader expects them instead of at the end of the alphabet.
Common questions
Does it change the original list?
No. The left box keeps your input; every operation writes to the right box.
Can I deduplicate a list of emails?
Yes, and the case-insensitive option is the right choice there, since email local parts are usually treated as case-insensitive in practice.
